What would win in a fight a serval or a hyena?

I saw a video on youtube of a serval and a hyena coming into contact with each other and they didnt fight. I umed it was because it would be too risky for either one. If they had fought, which one would win? I am leaning more towards the serval because it is faster, more agile, and it hunts alone as suppose to hyenas that normally hunt in packs. Thanks
